Deduplication Table Quota

[pjedrzejczak-catalogicsoftware]

Hi,

Going thru the deduplication changes merged in 2.3 I could not find any information on how the new dedup_table_quota=auto setting works on Pools without any special or dedup vdevs at all. I tried figuring it out myself to no avail. I see that I was not entirely on my own because some other people also asked similar questions, but they were left unanswered.

Question #1
Question #2

Can someone explain to me how dedup_table_quota=auto works on Pools without dedup or special vdevs? My intuition tells me it is functionally equal to none, is that correct?

IIRC yes. At some point I proposed it to also consider memory size there, but it was not implemented at this point.

Thanks for taking the time, since I don't see any opposing opinions I will mark it as answered :)
